UB Diving provides professional scuba tank fills and specialty breathing gas and CCR support for divers across the Comox Valley and Vancouver Island.

With a high-capacity compressor system and proper gas blending equipment, UB Diving supports recreational divers, technical divers, and rebreather divers requiring reliable, high-quality breathing gas.

Air Fills

UB Diving provides clean, high-quality compressed air fills for aluminum and steel scuba cylinders. Single fills, multi-fill packages, and unlimited annual fill plans are available for frequent divers.

Nitrox Fills

Nitrox fills up to 36% are available for certified Nitrox divers. Nitrox is widely used by divers to extend bottom time and reduce nitrogen loading during repetitive dives.

Divers must present a valid Nitrox certification card before receiving Nitrox fills.

Trimix Gas Support

UB Diving supports technical divers requiring Trimix gas blending. Trimix is commonly used for deeper technical dives where reduced nitrogen and oxygen fractions improve diver safety and performance.

CCR Rebreather Cylinder Fills

UB Diving supports closed circuit rebreather divers requiring oxygen and diluent fills for small CCR cylinders.

Sean Smyrichinsky is a certified TDI Trimix and Nitrox gas blender with extensive experience supporting both recreational and technical divers.

Additional Fill Services

UB Diving can also fill compressed air tanks used for paintball and other compressed air systems.

Medical oxygen cylinders used for dive first aid kits and emergency oxygen units can also be filled.
